Application filed February 14, i906. Serial No. 301,092.

paratus, of whichthe following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My presentinvention relates to apparatus for use in the Hollerith tabulating system in which the data or items to be tabulated are denoted by index points formed upon a record usually in the form of a card, the indexi points being formed by punching holes in the record at predetermined points. The apparatus herein described and claimed is intended primarily for operation in connection with such records in which the value or amount of the items is determined by the location of the index points in rows, each row having index-point positions from 0 to 9 in value or amount and for the purpose of clearl describing theinvention,-I have selected a preferred form of apparatus embodying a series of registering elements or wheels of different orders or denominations upon which any item of amount or value will be registered upon the wheels by one operation of the apparatus, which is thus distinguished from apparatus intended only for the addition of units.

My present invention provides for the mechanical operation of the apparatus as distinguished from other formsv of apparatus inwvhich, for example, electrically or pneumatically operated devices are controlled or actuated by means of the indeX-' points of the record, but subject to this provision I 1 do not intend that my invention shall be limited to the specific .devices which I have. illustrated and described for effectingsuch mechanical operation of the ap vparatus. many of which may be departed from without any departure from the broad principles of iny'present invention.

In-the accompanying drawings which rep resent a preferrcdforin of apparatus embodying my invention, Figure 1 represents an elevation partly in section; Fig. 2 is a partial plan view; Fig. 3 is a front elevation of the registering mechanism; Figs. 4:

and 5 are respectively a rear elevation and a top plan view of a portion of the regis tering mechanism designed to show particularly the transfer or carrying devices; Fig. 6 is an end elevation of the machine, designed particularly to show those portions of the mechanism not clearly shown in the elevation represented in Fig. 1; F ig. 7 is a. sectional elevation of a modified form of machine; Fig. 8 is a plan view (it a detail of the machine shown in'Fig. T; Fig. 9 is a partial plan view of one of the records or cards, and Fig. 10 is a detail view show ing a modification.

Similar letters of reference are employed.

to designate like parts.

Referring particularly to the machine shown in Figs. 1 to (i inclusive, 1 represents the bed.plate or support for the record cards, the same being provided with perfo' rations or holes'Q and with stops 3 and 4, the former located at the right hand end and the latter at the rear side of the bed plate, for the purpose of insuring the proper positioning or centering of the record card. A movable pin box or platen 5 is suspended by a link 6 from a hand lever 7 that is pivoted at 8 to a rigid standard 9 and has box or platen in an elevated position. An arm 11 extending parallel to the hand lever is jointed at one end to the pin box and at the other to the rigid standard 9 and serves to steady the pin box during its upward f @530 provided with transverse rows of spring and'downward movements. The pin box is pressed pins 14, corresponding in number and relative arrangement to the perztorations in the bed plate 1. There'are preferably ten pins in each row having a value of from 0 to 9 as represented in Fig. 1.

A record card 15, such as I preferably use is partially shown in Fig. 9. Upon its sur face are marked or printed a series of trans verserows of index-point positions corre spending .in number and relative position to the series of rows of holes or perforations in the bed'plate, each row like those of the bed plate comprising index-point positions from 0 to 9 in value. In the preparation of the card it is intended that an index-point shall he punched out in each of the rows pins will come in contact/With the imperfo-- rate portions of the card {and will be forced back within the pin box, and thus rendered inoperative so far as that card is concerned.

Below thebed plate and at one side there of are arranged a. series of Whatmay he termed register actuators, consisting as shown in Fig. 1, of movable telescopic. bars,

each composed of two sections, a bar 17 and a sleeve 18, held normally extended by aninterposed spring 19. These register actuators are as many in number as there are series of pins in the pin box, that is to say, there is a register actuator for each transverse row of pins. Upon each bar 17 is formed or attached a rack 20 which meshes with the teeth of a movable sector 21 hungso as to turn freely upon a shall. and carrying a pawl 23 which 1sadaptcd to engage the teeth of a ratchet wheel, such as ill,

secured to or made integral with a'regi.-=tcr-. ing or counting wheel 25 adapted to carry upon its periphery two series of figures 'l'rom O to 9. The forward end of each bar .17 is guided by suitable guides 27, arral'iged beneath the bed plate as shown in Figs. 1 and 3, while its rear end slides telescopically,in the sleeve 18 which is supported by a cross bar 28, its extremity being screw threaded to receive nuts 2f) as shown in Figs. l and Q,

The cross bar 28 extends from side to side of the machine and its ends are formed into slides 30 which are adapted to more back flainluforth on ways 3t, (l igs. land 3) A hand lever 32 is connected .to the slid csilo oi the cross bar by means of links Ill).

The operation is as follows: \Vhcu the perforaled record card is placed in proper posi tion upon the bedplate ol' the machine, and.

the pin box or platen is brought down upon it, oue pin oi each row in the pin box will pass down through the card and through the correspomling pcrtoralions in the bed plate into the path of the movable bars 17. the bars l7 are then simultaneously advanced by pulling forward the lever It! and ea h ar 17 is advanced until intercepted by the pin projectangin its pathu'ay, lheamount of its forward motion being u-oporl-|onal to the location of the pin which is determined by the value of the hole punched in thr given row or column in therard;

only a single hand lever may be required to perform all the necessary operations. Such Y a modification of the invention is illustrated in Figs. 7 and 8 which show the pin box or platen 5 provided with-the spring pins 14 and the perforated bed plate 2.- Below the bed plate are arranged a series of bars 50 whose forward ends. have ratchet teeth 51- on the upper side and rack teeth 52km the under side The forward end of each of these bars is suitably guided in guides 33- while its rear end passes through a fixed guide 54-. Between a collar 55 upon each of these barsyand the fixed guide 54 isarranged a spring fit whose tendency is to force the bar forward. Iivoted-tocne side ='of the bed plate is a series of pawls 5.8, there being one for each bar. The rear end of each'of, these pawls is adapted to. engage with the ratchet teeth on its cooperating-bar,

while its upper or forward end 39 projects within the path of the pin box so that it will be struck when the pin .box is depressed.

Beneath the bed plate-at opposite ends of the machine are arranged guides upon which are adapted to travel slides 61 that are connected by a cross bar 62 shown in dotted. lines Fig. 7), extending from end to end of the machine and in thepath "of pr ojections 63 depending .from the movable bars. Jointed to the slides 61 are bell crank levers Q5 pivoted at 66-a nd having their lowermembers connected by'bars (3 7 to. the hand lever of opgrating handle 7, The rack teeth of the bars are. adapted to engage with the gear segments forming part of the'hcrclIlbOfOIG described registering mechanism.

hand lever, the slides 61 and cross bar 62 are moved forward to the front of the ma-- chine as shown indotted lines, (Fig. 7).

After the appropriate pins of the pin box have passed through the holes 111' the record card and through the holes in the bed plate,

'so that they projeotbelow the lower surface of the bed plate,.the pin boxcontinues itsv downward movement until it strikes the "projections 59 of-the pawl 58 "and releases all of them from. their respective bars, the latter then, undertheinfluence of their springs advancing a greater or less distance, according to the position of the particular pin in the. path of each,'until arrested by said pins. When new the handlever is raised, theslides 61 and cross bar, 62 move backward, the cross barengagingthe pro- 'jections 63- on the actuating bars one after, another and carrying the bars back to their initial positions, this backward movement of the ba-Is'causingan advance of the registering mechanism connected to each, proportioned to theydistance each. bar travels as willbe readily understood. The effect of;

thus carrying the bars bafckto initial posi tion' is to again compress. their operating springsand reengage them'with their retaining awls. As will be seen by inspection of l ig. 7, the tooth of each act uator bar is made shorter than the succeeding teeth so that when the first pin (standing for O) ,of the row of pins in the pin box. comes'down through the corresponding first liolein the bed plate, the bar that is to en gage it will, when released by the operation of the pawl, move forward only the length of the short tooth or so as -.to bring the second ratchet tooth in position to he engaged by the pawl when the pin box is raised again, this amount of movement being, how-. ever, insuiiicient to cause the pawl 23 ig. I) carried by the gear sector21 to engage the next-succeeding tooth'of .the ratchet wheel 24, the result being that when the actuator bar is moved back to its initial position by the backward motion oi the: cross bar 62, the said pawl 23 will make a "dead stroke and no change of position of the registering wheels will take place.

In the apparatus above described, the pins '14 act as stops toydetermine the operative movement of the actuators;.but aswill be understood, it -is not; essential that the pins 14 should d rectly engage the actuating bars 17 orarrest their movement, since intermediate devices, actuated mechanically by the pins, may be provided to determine the extent of movement imparted to the registering elements or wheels by the actuating bars or actuators at each operation. I have shown on an enlarged scale in Fig. 10 a construction in which suclrintermediate devices are employed. In this instance,- they serveto arrest the movement of the actuators. In

the modification shown the holes in the bed plate are enlarged and in each of them is supported,hy a coil spring 70, a plunger 71. When the pin box is depressed,-the pins 14 will on age such ofthe plungers 71 as lie under t e perforations injthefsecond card,
